Answer:
37.5% decrease
Step-by-step explanation:
The percentage change is given by the formula ...
pct change = ((new price) -(original price))/(original price) × 100%
= (50 -80)/80 × 100%
= -3/8 × 100% = -37.5%
The negative sign indicates a decrease.
The decrease in price is 37.5%.
y>6
Simplify so 5y-2(y)-2(4)>10
3y-8>10
3y>18

The rule (x, y ) → (x + 4, y - 6 )
means add 4 to the original x- coordinate and subtract 6 from the original y- coordinate, thus
P(- 8, 3 ) → P'(- 8 + 4, 3 - 6 ) → P'(- 4, - 3 )
Q(- 8, 6 ) → Q'(- 8 + 4, 6 - 6 ) → Q'(- 4, 0 )
R(- 3, 6 ) → R'(- 3 + 4, 6 - 6 ) → R'(1, 0 )
-5, -2, and 0
the cycle repeats every 4
19/4 = 4.75
16 is divisible by 4 plus three more
thus but you problem has a minus in front so "i"
